32 MHz Cortex-M0+ with 192 KB flash — the battery-life trade-off
The STM32L071CZT6 runs an ARM Cortex-M0+ core at 32 MHz, with 192 KB of program flash and 20 KB of SRAM — enough for a modest sensor-fusion stack or a single-protocol wireless node without external memory. The 6 KB on-chip EEPROM holds calibration constants or configuration data that survive power loss without a separate serial EEPROM on the board.
Industrial temperature grade and 48-LQFP footprint
The 13-channel 12-bit ADC covers multi-sensor analog front-ends without an external multiplexer; the internal oscillator eliminates the crystal for applications that can tolerate the ±1% accuracy.
